A year ago I posted and my purchase decision took a twist. I deleted the idea of getting a case-keyboard combo and just got a bluetooth keyboard. I love it! (Photo & info below).
Very light.
Nice keyboard typing feel (and I'm fussy about that)
Illuminated...different that just Backlit. Light shines through the keys and I really like it...never had 'illuminated (a new feature, I think), nor backlit keyboard before.
The other obvious great feature is that with one keystroke it will switch from working with my iPhone, my desktop, and my iPad -- and it does, and I understand this use to be a hassle but this is my first wireless/bluetooth keyboard and I now just take it for granted: To me, this is how it should be.
As far as covers go, I just carry iPad in nice shoulder bag. (I'm now interested in getting a stand and finally saw one that was exciting...like an old fashioned type of 'document holder,' - it seems like it would really not just set the iPad up but allow it to be moved all around...sort of like a ghoosneck lamp.
What I didn't expect but also quickly realized, it's nice the keyboard is not attached to a case...much more flexibility than some keyboard/case combo models...I've done typing while sitting up in bed and the iPad is across the room (I don't see...or need to see the screen)...there is some 'freedom in that.'
Um...I do make check to make sure it's working right. I use Pages for such typing. Synch to iCloud.
Good luck in your choice...I really held out until I saw something that I thought was 'cool,' and I'm glad I did.
So, imo, if you want to take a 'twist' in your purchasing, you should be happy with the
